Frequently asked questions about this product
Are all the ports on the HP 1920-24G-PoE+ powered?
Yes, all 24 Gigabit ports are PoE+, up to 30 W each, within a 370 W budget. They are joined by 4 Gigabit SFP slots for fibre uplinks and a dedicated RJ-45 console port for local management.
How much electrical power does this switch require?
474 W maximum, including the 370 W of PoE. Size the UPS and the wiring-closet circuit on this figure: at this port density, the switch draws as much from the power supply as a small server.
How is this switch managed?
Through a web interface, command line, Telnet or SNMP v1, v2c and v3, with HTTPS and TFTP for transfers. Authentication goes through SSH or RADIUS, and an RJ-45 console port lets you regain control when the network is down.
What latency and performance does this model offer?
56 Gbps of capacity and up to 41.7 Mpps, with latency below 5 µs at both 100 Mbps and Gigabit. The MAC address table holds 8,192 entries, on a 500 MHz MIPS processor with 128 MB of memory.
How much rack space does this switch take up?
440 × 260 × 44 mm and 3.4 kg: 1U high and 26 cm deep, which fits in a deep wall-mount cabinet. It mounts in a standard 19-inch rack.
Is the switch new and covered by a warranty?
Yes, new equipment, with the invoice serving as the warranty document. This is the HP 1920-24G-PoE+, part number JG926A, a switch managed through a web interface, with 32 MB of flash memory.
Managed access switch designed for SMEs and branch offices: powers workstations, Wi-Fi access points and IP cameras over Power over Ethernet, with centralised control from Aruba Central and automated deployment.
•Managed via Aruba Central (cloud or on-premise), web GUI, CLI and REST API
•PoE+ up to 30 W per port (IEEE 802.3af/at, class 4)
Fast PoE instantly powers cameras, Wi-Fi access points and IP phones over the network cable, with no break on restart. Four 10G links absorb traffic to the network core. Web, cloud app or command line control, built-in DoS/802.1X security.
Managed switch that keeps your PoE equipment powered even during a restart (perpetual PoE), for continuity of service on critical cameras or Wi-Fi access points. Configurable through the HUAWEI eKit App cloud or locally.
Covers a whole floor of cameras, Wi-Fi access points and IP phones on a single device, without multiplying power units. 10G links and a capacity of 176 Gbps absorb the combined traffic. VLANs, security and administration of enterprise equipment.
Managed switch that powers its ports over PoE+ through the network cable, with two 2.5 Gbps combo ports for recent Wi-Fi access points. Configurable through the HUAWEI eKit App cloud or locally.
Designed for SMEs and video surveillance, in a 19″ rackable format: automatic IP camera recognition, PoE consumption alarm and remote port restart through Ruijie Cloud.
Designed for SMEs and video surveillance: automatic IP camera recognition, loop prevention and remote port restart through Ruijie Cloud. Extension up to 250 m in camera mode.
